Suppose there are 20 consumers for a good and they have identical demand d(p) = 10 - 3p for any price less than or equal to 103 and d1 (p)=0 at any price greater than 103. What is the market demand function?
In the given demand function, the consumers demand only when price is either less than or equal to 103. Therefore, market demand will be
(d) Market demand
(p) = 20[d(p)]
(p) = 20(10 - 3p)
(p) = 200 - 60p
for any price less than or equal to 103.
Market demand (p) = 0 at any price greater than 103.
